What it covers

Reference numbers and names of welding, cutting and allied processes.

Key points for fabricators

Numbers are independent of language, so they are ideal on multilingual documents.

Welding processes in the WPS register and in consumable estimates (SMAW, GMAW, FCAW, SAW, GTAW) correspond to these process numbers.
